Effects of drying methods on the vitamin and provitamin compositions of selected vegetables during storage were assessed in this study. Telfaria occidentalis, Celosia argentea (green), Vernonia amygdalina, Moringa oleifera, Launaea taraxacifolia, Curcubita maxima and Celosia argentea (red) were subjected to air drying (AD), oven drying (OD) and freeze drying (FD). The experiment was a 3x7 factorial arrangement in a completely randomized design. Dried leaves were milled and assayed for vitamins (pyridoxine, riboflavin, ascorbic acid and tocopherol) and provitamins (total carotene and ergocalciferol). Samples were stored in opaque airtight containers after drying and assayed periodically at weeks 0, 3, 6, 9, 12, 15 and 18 of storage. Air-dried samples had significantly higher (P<0.05) total carotene (1177.49 ?g/100g), pyridoxine (0.59 mg/100g), riboflavin (0.46 mg/100g), ascorbic acid (39.11 mg/100g), ergocalciferol (46.55 ?g/100g) and tocopherol (57.52 ?g/100g) compared with samples dried by other methods. Moringa oleifera leaf type had significantly higher (P<0.05) total carotene (1079.48 ?g/100g), riboflavin (0.41 mg/100g), ergocalciferol (46.40 ?g/100g) and ?-tocopherol (58.45 ?g/100g) while Cucurbita maxima had significantly higher (P<0.05) pyridoxine (0.73 mg/100g). Effects of the interaction of drying methods and leaf type were significant (P<0.05) on the vitamin and provitamin compositions of samples. The effect of the interaction of the oven drying method and leaf type was highly significant (P<0.05) on inherent vitamin and provitamin of samples. Vitamin and provitamin compositions of samples were stable until week six. Air-dried samples contained more vitamins and provitamins which were also more retained in storage.

Fresh tomato fruits have a very limited shelf life partly due to their high moisture content and respiration rate. A possible way of storing tomato fruits is to dry and process them into powder or paste. Therefore, this research was conducted to determine the effects of drying methods and packaging materials on physical and sensory qualities of powdered tomato in Yola, Adamawa State, Nigeria. Harvested fruits of tomato variety, “Rio de grande” were subjected to blanching and subsequent drying methods and packaging materials. The experiment was laid out in a Completely Randomized Design (CRD); with the drying methods placed in main plot while the packaging materials in sub-plot and repeated three times before storage for twelve weeks. At four weeks of storage, oven drying method was found to be statistically different (p≤0.05) in terms of water absorption capacity value of 3.19 (mg/100g). The glass jars performed better than polythene bags in color retention, taste and consistency at four weeks of storage. The study shows that tomato fruits can be successfully dried using oven, sun and shade drying methods but preferably oven drying method. The processed powder could be successfully stored for 12 weeks or above using either glass jars or plastic container without affecting the consumer appeal and this will also reduce the postharvest losses of tomato fruits.

ABSTRACT Fruits provide not only essential nutrients for food, but also bioactive compounds that promote health benefits and help reducing the risk of developing non-communicable chronic diseases. In this sense, this work aimed at quantifying bioactive compounds during the maturation of four fruits native to the Restinga forest of Ceara. Myrtle fruits (Eugenia punicifolia (Kunth) DC.) were collected at the Botanical State Park of Ceara, Caucaia-CE, and guajiru (Chrisobalanus icaco L.), manipuça (Mouriri cearensis Huber) and murici-pitanga fruits (Byrsonima gardneriana A. Juss.) at the Botanical Garden of São Gonçalo, São Gonçalo do Amarante-CE. Fruits were collected at different stages (E) and transported to the Laboratory of Plant Ecophysiology, being characterized into five or six maturation stages according to the bark color, then processed and frozen for the following physicochemical and chemical evaluations: ascorbic acid, total chlorophyll, total carotenoids, total anthocyanins and yellow flavonoids. A completely randomized design was used, with five or six treatments, depending on the maturation stages of fruits and four replicates. Murici-pitanga had higher contents of ascorbic acid (ascorbic acid 646.23 mg/100 g E5), total carotenoids (6.13 mg/100 g E5) and total anthocyanins (7.99 mg/100 g E2); and myrtle had higher contents of total chlorophyll (11.05 mg/100 g E1) and yellow flavonoid (69.11 mg/100 g E2). There are positive and significant correlations between chlorophyll and carotenoid (R= 0.99; P <0.01) for manipuça and between anthocyanin and yellow flavonoid (R= 0.97; P <0.05) for murici-pitanga fruits; however, the correlation is negative and significant between ascorbic acid and yellow flavonoids (R= -0.98; P <0.05) for myrtle fruits. It could be concluded that murici-pitanga and myrtle fruits had the highest contents of bioactive compounds with the highest levels, therefore both fruits can be recommended to be commercially exploited by the food, cosmetic and phytomedicine sectors.

This studywas carried out to determine the utilization and the optimumlevel of offer of bitter leaf (Vernonia amygdalina) meal (BLM) by West African Dwarf (WAD) goats. In a 20-week trial, twenty four WAD goats of both sexes, 5-7 months old, were randomly allotted to four treatments of graded levels of BLM(0% BLM(Control diet), 15% BLM, 30% BLMand 45% BLMdiets) in a completely randomized design to determine the utilization of bitter leafmeal as feed for goats. The dietswere used as supplements to a basal ration of Panicummaximum. Two digestibility trials were carried out. The digestible ether extract intake and digestible organic matter of goats on 0% BLM were significantly (P<0.05) higher than the values obtained for goats on bitter leaf meal diets. The average daily weight gain (g/day) for goats on 0% BML was significantly (P<0.05) higher than that of others. There were significant (P<0.05) differences in the percentage mortality of the goats fed experimental diets. The percentagemortality of goats on 30% and 45%BLMwere significantly (p<0.05) higher than that of others. It is concluded that bitter leafmeal can be included in the diets of (WAD) goats up to15%without any deleterious effect.

The herbs, Chenopodium album Linn. and Spinacia oleracea Linn. belongs to Chenopodiaceae family, are the two nutritious and edible green leafy food crops, abundantly found especially in the northern-west region of India. These plants have gained renown popularity, because of their high nutritional content including protein, amino acids, carbohydrate, and even the presence of phenolic components, which ultimately may get affected with drying and storage techniques. Impact of different drying methods (microwave drying at 4 minutes, hot air oven drying at 5 hours and sun drying at 8-10 hours) on nutrient quality and antioxidant property of Chenopodium album Linn. and Spinacia oleracea Linn. leaves were evaluated by using UV spectrophotometritc assay, total phenolic content and DPPH free radical scavenger method. Drying treatments were significantly decreased the moisture, carbohydrate and protein content present in C.album and S. oleracea. Hot air oven drying method produced dried samples of C.album and S. oleracea had significantly similar antioxidant activity when compared with the samples obtained from sun drying method. The dried samples obtained from hot air oven drying technique showed significant presence of total phenolic content in C. album and S. oleracea (6.44±0.12 mg/g, 6.69±0.40 mg/g) whilst the traditional sun drying method produced 8.00±0.02 mg/g and 7.89±0.37 mg/g). It is concluded that microwave drying and hot air oven drying were the methods to preserve appreciable percentage of nutrient components compared to the fresh samples. On other hand, the traditional method produced substantial reduction of nutrient quality. From statistical analysis, hot air oven drying technique was considered as optimum method which showed satisfactory % retention of protein (65.86%) and carbohydrate (85.95%) at 5 hours (shorter time than sun drying time period) along with significant antioxidant activity (34.89 μg/mL and 35.60 μg/mL) similar as obtained from the traditional technique (32.00 μg/mL).

Flowers, leaves and fruits of hawthorn plant are traditionally used for treating diseases like hypertension and atherosclerosis. The medicinal effects of the plant are generally attributed to its phenolic compounds. However, the fruits are perishable materials because of their high content of water, and generally dried and stored to be used outside its season. The main aim of this research was to investigate the effect of different drying methods on phenolic compounds of the hawthorn fruit. Fruits were collected from the wild growing trees in Turkey. De-seeded fruits were dried in freeze-, oven- (60 oC) and microwave pretreated oven drying (microwave application for 5 min at 360 W before drying at 60 oC) methods and analyzed for antioxidant activity, phenolic compounds, total phenolic content and color parameters. Total phenolic content of fresh hawthorn fruits was found as 13.36 mg g-1 DW. Oven- and microwave pretreated oven drying methods had a reductive effect on total phenolic content and antioxidant activity of fruits when compared to freeze drying method. (-)-Epicatechin (994.10 mg kg-1 DW), rutin (765.30 mg kg-1 DW), and procyanidin B2 (553.80 mg kg-1 DW) were the main phenolics of the fruit. Lowest values of these three compounds were observed in oven-dried fruits. Microwave pretreatment oven drying method resulted in browner product. Although the highest phenolic concentration and antioxidant activity were occurred in freeze-dried sample, microwave pretreatment before oven drying could be applied to reduce the time and cost of drying in terms of phenolic compounds and antioxidant activity.

The aim of this study was to determine a change that occurs in total phenolic content (TPC) and antibacterial activity of ashitaba (Angelica keiskei) after dried using two different methods : sun and oven drying. The effectiveness of the drying methods was evaluated in term of total phenolic content (TPC) by using spectrophotometric assay with Folin-Ciocalteu reagent and antibacterial activity againts Streptococcus mutans by in vitro macrodilution assay. Oven drying at 60oC possessed high TPC (2,98 ± 0,0935 g EAG/100g) compared to sun drying method (1,72 ± 0,0142 g EAG/100g). Simillar pattern was also observed in antibacterial activity. Oven drying have higher antibacterial activity with the MBC (minimal bactericidal concentration) value of 0,5 mg/mL againts Streptococcus mutans. Therefore, sun drying is not suggested for drying method of ashitaba in terms of total phenolic content and antibacterial activity compared with oven drying methods.
